COFFEE-POT.

Specification ofrLetters Patent.

Patented June 23, 1908.

Application filed December 20, 1906'. Serial No. 348,781.

nati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Coffee- Pots; and I do hereby declare thefollowing to be a full, clear,

and exact description of the invention, such as will enable 0thers,skilled in the art to which it appertains to make and use the same. p

This invention relates to improvements in pots for the )roduction-of infusible beverages, especia y coffee, and moreparticularly relates to pots of that type commonly termed, drip pots.

The object of the present invention is to provide a pot of the character mentioned the construction of which is such that the beverage, ready for serving, may be produced in an expeditious manner and without the presence therein of the grounds incident to lnfusion; and, moreover, the invention further aims to provide a pot by which the bev erage may be made in immediate successive quantities without the necessity of separating the sections of the pot for cleansing.

A further object of the present'invention is the provision of a mixer for beverages capable of usewith ots of the usual form, thus rendering it possible to convert the ordinary pot of commerce into a pot of the"drip type with but slight expense, and without t 1e necessity of altering the construction of the ordinary pot. 1 p

eneral objects in view, and others which Wlll appear as the nature of the improvements is better understood, the in- I h the present invention. Fig. 2 is a vertical vention consists substantiallyiri the novel construction, combination and arrangement of parts hereinafter described, illustrated in the accompanyin drawings, and pointed transverse sectional-view thereof. Fig. 3 is a top plan view of the removable bottom of the mixer section. transverse sectional view illustrating .a modified construction. Fig. 5 is a transverse sectional view of another form of supporting basket. tional view illustrating theuse of the mixer section withthe ordinary ot of commerce.

Referring in detail to t e drawings, the

Fig. 4 'is a fragmentary- Fig. '6 is a vertical transverse sec-' numeral 1 designates the container section of the herein-described pot, said section being provided with a pouring spout 2 and a handle 3, as in the construction of pot commonly employed.

a mixer section 4, said section being arranged in'sup'erimposed relation to the container section 1 and ta ering slightly from the top to its bottom. his permits the diameter of the mixer section to slightly decrease in a downward direction for a purpose to be presently stated. It will beobserved that the lower end of the mixer section 4 projects into the top of the container section to a slight extent, and interposed between the lower end of the mixer section 4 and the upper end of the container section 1 is a supporting basket 5 formed preferably of wire fabric oflarge mesh. This basket may be formed entirely of wire fabric, or, in lieu thereof, it may be formedas shown in Fig. 5, in which view it will be seen that the sides are imperforate, being made preferably of tin, the bottom being formed of wire fabric suitably secured to the sides. The basket 5 fits snugly within theuppor end of the container section 1, while the lower end of the mixer section 4 fits snugly within the basket 5, and a strainer 6, formed preferably of textile material, such as muslin, envelops the lower end of the section 4 to prevent the grounds passing into the container section, as will be presently explained. It will be its edges do not project beyond the edges of the supporting basket 5 and the sidesof the section 4, being concealed'thereby, but the dimensions of the strainer are such that when the lower end of the section 4 has been inserted into the basket'5 the strainerfi will be drawn taut over the lower end of the section 4. While the strainer 6- has been described as'of textile material, such as muslin, .it is manifest that wire fabric of very fine mesh maybe substituted therefor, thusdispensing with the use of textile material.

The mixer section 4 is rovided with a removable bottom 7, whic bottom is in the form of a shallow cup, and the sides of said bottom are tapered to conform to the tapering sides of the sections 4, so that when the bottomf7'is moved, to a point within the section 4 corres onding in .diameter substantiallyto the diameter of said bottom, the

1 sides of the latter will snugly fit against the Associated withthe container sectionl is noted that the strainer'6 isof such size that sides of the section 4 and close communication between the interior of said section and the container section 1.

An 0 erating bar 8 is employed for mov-- ing the ottom 7, said bar being formed of a plurality of wires, preferably three, twisted together, the lower ends of said wires diverging and being connected to the sides of the bottom 7 at spaced intervals, as by soldering, or in an equivalent manner. The bar 8 passes through a centrall -disposed aperture- 9 formed in a removab e cover 10, which serves to close'the upper end of the mixer section 4, which cover is provided with a handle knob 11, or its equivalent, for removing and replacing the cover, and ar-' ranged upon the cover 10 is a resilient ret'arder 11" in the form of a leaf spring. One

tom 7 has been moved to and from its seat within the mixer section 4.

In Fig. 4 is illustrated another form of the invention. This form, however, is, in the main, recisely the same as in the other views, ut it will be noted that the section 4 is provided with an annular bead or indentation 13, upon which the removable bottom7 is seated when in its closed position. In this case, however, the sides 14 of the bottom 7 have a greater inclination than that of the sides of the bottom in the other form, thus ermitting the section to be readily seated upon the bead 13 when forced to its closed position, and establishing a perfectly tight joint between the bottom and said bead to preclude the liquid mixture passin downwardly to the container section unti the removable bottom has been displaced from the bead.

The mixer section 4 is also provided with a seriesof graduations 15 in the form of beads and lines, whichv graduations indicate in cups, pints, or quarts, as may be desired, the oints to which the section 4 may be supp ied with boiling water for the roductionof a determinate amount of t e beverage.

Fig. .6 discloses the use of the mixer section 4 with the ordinary 0t of commerce, the latter being designated by the numeral 16. When used in this relation the ordinary ots of commerce may be readily converted into drip ots, it being merely necessary to accommodhte the mixer section 4 to pots of proper size, and to this end the mixer section may be made in sizes'to correspond with the ordinary size of commercial pots. When used in this relation, thestrainer 6 is employed with the mixer section to free the grounds from the liquid when infusion has taken place, and by merely increasing the size of the strainer 6 so that the edges thereof may roject beyond the edges of the pot 16,

and t e sides of the section 4, the use of the su porting basket 5m ay be dis ensed with;

n. the use of the herein-descrl ed pot, the

parts are assembled as illustrated in Fig. 2, in whichfigure it will be noted that the strainer 6 is drawn across the lower end of. the mixer section 4 and supported within the basket 5, which latter in turn issu ported within the container section 1. Pu verized or finely ground coffee having been placed within the mixer section 4 in a suitable quantity, the position of the -bottom 7 being such as to prevent communication from'the interior of the section 4 above the bottom with mixture of coffee and water is permitted to stand for a short period, say, for approximately one-half or threequarters of a minute. the strength of the coifee, and after lapse of the period referred to pressureis a plied to the operating bar 8 in an upward irection, whereupon the movable bottom 7 moves'up wardly from engagement with the tapering sides of. the mixer section 4 and establishes communication between the interior of said section and the container section 1. The infusion is thus permitted to pass down between the sides of the bottom 7 and the sides of the section 4 upon the strainer 6, at which point the grounds'are effectually'separated from the liquid, and the latter passes down into the container section 1, the mesh of the basket 5 being large in order to permit free passage of the liquid, from which section it may be poured through the spout 2. After the beverage thus produced has been removed from the container section 1, it is possible to prepare a new infusion without the necessity of separating the parts, it being merely necessary to again seat the bottom 7 This enables the water to extract tity of boiling water, a like 0 eration 1s repeated, after the mixture of t e coffee with the water, and the coffee, prepared for serving, may be drawn from the container section 1, as before described.

In separating the parts, the mixer section 4 1s first removed, leaving the strainer 6*iii the supporting basket 5, and through the 5' medium of the latter, it is apparent that the strainer 6 will still be prevented fallingig-into the container section 1, or dumping the grounds into the clear coffee therein, and manifestly in removing the supporting basket 5 from the container section. 1, the

strainer 6 will be-simultaneously removed therewith.

-It will beapparentthat the herein-described invention'may also be employed' as a tea-pot, and in producing the same, any suitable material may be employed, sucli'as tin,

. aluminum, granite or" enameled ware.
